ABSTRACT

An apparatus and method are provided for transmitting and receiving a quasi-cyclic Low Density Parity Check (LDPC) code in a multimedia communication system. In the method, a signal transmission apparatus generates a quasi-cyclic LDPC code, and transmits the quasi-cyclic LDPC code to a signal reception apparatus. The quasi-cyclic LDPC code is generated by encoding an information word vector using a child parity check matrix, generated by performing one of a scaling operation, a row separation operation, and a row merge operation on a parent parity check matrix. In the scaling operation, a size of the child parity check matrix is determined. In the row separation operation, each of rows included in the parent parity check matrix is separated. In the row merge operation, the rows included in the parent parity check matrix are merged.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an apparatus and method for transmitting and receiving a quasi-cyclic Low Density Parity Check (LDPC) code in a multimedia communication system, and more particularly to a quasi-cyclic LDPC code transmission and reception apparatus and method that support various codeword lengths and code rates.

2. Description of the Related Art

A multimedia communication system, for example, a Moving Picture Experts Group (MPEG) Media Transport (MMT) system provides various large-capacity content, such as High Definition (HD) content, Ultra High Definition (UHD) content, etc. Further, according to a diversification of this content and especially increases in large-capacity content, data congestion has become a more serious issue. As a result of the data congestion, content transmitted by a signal transmission device is not always completely transferred to a signal reception device, and some of the content is lost en route.

In general, data is transmitted on a packet basis, and accordingly, data loss is generated on a transmission packet basis. For example, if the transmission packet is lost on a network, the signal reception device cannot receive the lost transmission packet, and thus, cannot know the data within the lost transmission packet. As a result, user inconvenience occurs, such as audio quality deterioration, video quality deterioration, video break, caption omissions, file loss, etc.

Therefore, the MMT system may enhance system reliability using various error-control schemes in order to reduce information data loss that is often caused by an error that occurs on a network according to channel status. A typical example of an error-control scheme is an Application Layer-Forward Error Correction (AL-FEC) scheme.

However, a multimedia communication system, such as an MMT system, requires usage of a Forward Error Correction (FEC) code supporting a codeword length and a code rate, which vary according to a code rate and delay time required by a service.

Further, when a conventional AL-FEC scheme is used, a signal transmission and reception apparatus should use different FEC codes according to a codeword length and a code rate, thereby increasing the complexity of the MMT system.

Consequently, it is difficult to implement an MMT system due to this increased complexity.

Referring to FIG. 1, a quasi-cyclic LDPC code generator includes a quasi-cyclic LDPC encoder 111 and a parity check matrix generator 113.

The parity check matrix generator 113 also receives the control information, converts a prestored base matrix into a parity check matrix, based on the control information, and outputs the converted parity check matrix to the quasi-cyclic LDPC encoder 111.

The quasi-cyclic LDPC encoder 111 generates a quasi-cyclic LDPC codeword vector by quasi-cyclic LDPC encoding the information word vector using the received control information and converted parity check matrix.

Additionally, although FIG. 1 illustrates the control information being input from the outside to the quasi-cyclic LDPC encoder 111 and the parity check matrix generator 113, alternatively, the quasi-cyclic LDPC encoder 111 and the parity check matrix generator 113 may prestore the control information, and in this case, need not receive the control information from the outside.

Further, although FIG. 1 illustrates the quasi-cyclic LDPC encoder 111 and the parity check matrix generator 113 are shown in FIG. 1 as separate units, the quasi-cyclic LDPC encoder 111 and the parity check matrix generator 113 may also be incorporated into a single unit.

Referring to FIG. 2, a parity check matrix generator 113 includes a parent parity check matrix generation unit 211, a parity check matrix generation unit 213, and a conversion information generation unit 215. The parent parity check matrix generation unit 211 reads a parent parity check matrix from an internal storage unit, or generates the parent parity check matrix using a preset scheme, and outputs the parent parity check matrix to the parity check matrix generation unit 213.

In accordance with an embodiment of the present invention, a parent parity check matrix Q is generated using a base matrix B, which includes K columns and M rows, and each of K columns maps to an information symbol block. Each element included in the base matrix B has a value of 0 or 1, and locations of elements with a value of 1 in each of the M rows may be expressed as a sequence, as shown in Equation (1). R _(i) ={j|0≦j<K,B _(i,j)=1}={r _(i,0) ,r _(i,1) , . . . ,r _(i,Di−1)}  (1)

In Equation (1), j denotes a column index, i denotes a row index, R_(i) denotes a sequence indicating locations on which elements have value 1 on the base matrix B, B_(i, j) denotes elements included in the base matrix B, and r_(i,Di−1) denotes elements included in the R_(i). The D_(i) denotes a degree of the ith row.

For a base matrix B including 10 columns and 4 rows, the base matrix B may be expressed as shown in Equation (2).

$\begin{matrix} \begin{bmatrix} 1 & 0 & 1 & 0 & 1 & 0 & 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & 1 & 0 & 1 & 0 & 1 & 0 & 1 \\ 0 & 1 & 1 & 0 & 1 & 0 & 0 & 1 & 1 & 0 \\ 1 & 0 & 0 & 0 & 0 & 1 & 1 & 0 & 0 & 1 \end{bmatrix} & (2) \end{matrix}$

Each of R₀ to R₃ in Equation (2) is expressed as shown in Equation (3). R ₀={0,2,4,6} R ₁={1,3,5,7,9} R ₂={1,2,4,7,8} R ₃={0,5,6,9}  (3)

The parent parity check matrix Q includes K×L columns and M×L rows, and is generated by substituting one of an L×L permutation matrix and an L×L zero matrix for each element B_(i,j) included in the base matrix B. The L×L permutation matrix is expressed as shown in Equation (4), and the L×L zero matrix is expressed as shown in Equation (5).

$\begin{matrix} {Q_{i,j} = \begin{bmatrix} 0 & 1 & 0 & \ldots & 0 \\ 0 & 0 & 1 & \ldots & 0 \\ \vdots & \vdots & \vdots & \ddots & \vdots \\ 0 & 0 & 0 & \ldots & 1 \\ 1 & 0 & 0 & \ldots & 0 \end{bmatrix}^{P}} & (4) \end{matrix}$

In Equation (4), P denotes an exponent, a related permutation matrix is an identity matrix if P=0, and a related permutation matrix is a zero matrix if P=−1.

$\begin{matrix} {Q_{i,j} = \begin{bmatrix} 0 & 0 & 0 & \ldots & 0 \\ 0 & 0 & 0 & \ldots & 0 \\ \vdots & \vdots & \vdots & \ddots & \vdots \\ 0 & 0 & 0 & \ldots & 0 \\ 0 & 0 & 0 & \ldots & 0 \end{bmatrix}} & (5) \end{matrix}$

For example, the parent parity check matrix Q may be expressed as shown in Equation (6).

$\begin{matrix} \begin{bmatrix} 0 & {- 1} & 0 & {- 1} & 3 & {- 1} & 3 & {- 1} & {- 1} & {- 1} \\ {- 1} & 2 & {- 1} & 2 & {- 1} & 1 & {- 1} & 1 & {- 1} & 0 \\ {- 1} & 3 & 1 & {- 1} & 0 & {- 1} & {- 1} & 2 & 3 & {- 1} \\ 1 & {- 1} & {- 1} & {- 1} & {- 1} & 2 & 0 & {- 1} & {- 1} & 1 \end{bmatrix} & (6) \end{matrix}$

In Equation (6), each permutation matrix is expressed as shown in Equation (7). −1≦P _(i,j) <L  (7)

In Equation (7), P_(i,j) denotes an exponent of a permutation matrix arrayed on a location at which the ith row included in the base matrix B and the jth column included in the base matrix B crosses.

A location and an exponent of each of permutation matrixes included in the parent parity check matrix expressed in Equation (6) may be expressed as a sequence, as shown in Equation (8).

T i = ⁢ { ( j , ) ❘ 0 ≤ j < K , > - 1 } = ⁢ { ( t i , 0 , e i , 0 ) , ( t i , 1 , e i , 1 ) , … ⁢ , ( Di - 1 , ) } ( 8 )

In Equation (8), T_(i) denotes a sequence indicating locations at which permutation matrixes are arrayed on the parent parity check matrix, t_(i,Di−1) denotes a location of a permutation matrix included in the ith row among permutation matrixes included in the parent parity check matrix Q, and e_(i,Di−1) denotes an exponent of a permutation matrix arrayed on a related location, i.e., a location which t_(i,Di−1) indicates.

Each of T₀ to T₃ is expressed as shown in Equation (9). T ₀={(0,0),(2,0),(4,3),(6,3)} T ₁={(1,2),(3,2),(5,1),(7,1),(9,0)} T ₂={(1,3),(2,1),(4,0),(7,2),(8,3)} T ₃={(0,1),(5,2),(6,0),(9,1)}  (9)

The parent parity check matrix generation unit 211 reads the base matrix B from an internal storage unit, or generates the base matrix B using a preset scheme.

As described above, the parent parity check matrix generated by the parent parity check matrix generation unit 211 only includes columns corresponding to an information symbol vector, i.e., an information part.

The conversion information generation unit 215 inputs control information, generates conversion information, and outputs the conversion information to the parity check matrix generation unit 213. The conversion information may include a scaling factor, a row separation factor, or a row merge factor, and a row separation pattern or a row merge pattern. If the conversion information includes the row separation factor, the row separation pattern is included in the conversion information.

If the conversion information includes the row merge factor, the row merge pattern is included in the conversion information. It will be understood by those of ordinary skill in the art that the row separation pattern and the merge pattern may be implemented in various formats.

A scaling factor S1 is used for determining a size of a parity check matrix to be generated by the parity check matrix generation unit 213. That is, the scaling factor S1 is used for changing a size of permutation matrixes and zero matrixes included in the parent parity check matrix Q. Here, S1 denotes a maximum integer satisfying k≦(K×L)/S1, where S1=2^(a), and “a” denotes a maximum integer satisfying k≦(K×L)/S1.

If the size of the permutation matrixes and zero matrixes included in the parent parity check matrix Q is L×L, the size of the parity check matrix to be generated by the parity check matrix generation unit 213 is L′×L′ according to the scaling factor S1. Here, L′=L/S1.

A row separation factor S2 is used for separating rows included in the parent parity check matrix, when the parity check matrix generation unit 213 generates the parity check matrix. Here, S2=ceil(m/((M×L)/S1)), where S2=2^(b), and b denotes a maximum integer satisfying 2^(b)≧ceil(m/((M×L/S1)).

For example, each of the rows included in the parent parity check matrix is separated into 2 rows, if the row separation factor S2 is 2.

FIG. 3 illustrates a row separation process according to an embodiment of the present invention.

Referring to FIG. 3, for the parent parity check matrix expressed in Equation (6), when a row separation factor S2 is 2, the first row 311 included in the parent parity check matrix is separated into 2 rows 313. In FIG. 3, C0 to C9 are indexes of each row of elements included in the first row 311, and C′0 to C′9 are indexes of each row of elements included in the 2 rows 313.

A matrix generated by performing a row separation operation and a scaling operation on a base matrix is equal to a matrix generated by performing the row separation operation on a parent parity check matrix, which is generated by performing the scaling operation on the base matrix. Therefore, a row separation pattern may be expressed using a row separated-base matrix or a row separated-parent parity check matrix.

A criterion for separating one row into n rows is shown in Equation (10). 1) T ₀ =T′ ₀ ∪T′ ₁ ∪ . . . ∪T′ _(n−1) 2)

∩T′ _(j)={ } for all 0≦

≠j<n  (10)

When Equation (10) is satisfied, one row is separated into n rows. That is, one row is separated into n rows expressed as shown in Equation (11). T ₀ →T′ ₀ ,T′ ₁ , . . . ,T′ _(n−1)  (11)

The row merge factor S3 is used for merging rows included in the parent parity check matrix, when the parity check matrix generation unit 213 generates the parity check matrix. Here, S3=ceil((((M×L)/S1)/m)), S3=2^(c), and c denotes a maximum integer satisfying 2^(c)≧ceil(((M×L)/S1)/m)).

For example, the rows included in the parent parity check matrix are merged on two-row basis, if the row merge factor S3 is 2.

FIG. 4 illustrates a row merge process according to an embodiment of the present invention.

Referring to FIG. 4, for the parent parity check matrix in Equation (6), when a row merge factor S3 is 3, the first row and the second row 411 included in the parent parity check matrix are merged into one row 413. In FIG. 4, C0 to C9 are indexes of each row of elements included in the first row and the second row 411, and C′0 to C′9 are indexes of each row of elements included in one row 413.

A matrix generated by performing a row merge operation and a scaling operation on a base matrix is equal to a matrix generated by performing the row merge operation on a parent parity check matrix, which is generated by performing the scaling operation on the base matrix. Therefore, a row merge pattern may be expressed using a row merged-base matrix or a row merged-parent parity check matrix.

A criterion for merging n rows into one row is expressed as shown in Equation (12). T _(i) ∩T _(j)={ } for all 0≦i≠j<n T′ ₀ =T ₀ ∪T ₁ ∪ . . . ∪T _(n−1)  (12)

When the criterion expressed in Equation (12) is satisfied, n rows are merged into one row. That is, n rows are merged into one row as shown in Equation (13). T ₀ ,T ₁ , . . . ,T _(n−1) →T′ ₀  (13)

If a row separation operation according to a row separation factor is performed, a row merge operation according to a row merge factor is not performed. If a row merge operation according to a row merge factor is performed, a row separation operation according to a row separation factor is not performed.

If a parity check matrix is generated according to a row merge factor or a row separation factor, a location and an exponent of each permutation matrix included in the parity check matrix are expressed as shown in Equation (14). (t′ _(i,j) ,e′ _(i,j))=(t _(i,j) ,f(e _(i,j) ,L,S1))  (14)

The parity check matrix generation unit 213 converts the parent parity check matrix output from the parent parity check matrix generation unit 211 into a parity check matrix using the conversion information output from the conversion information generation unit 215.

If a parity check matrix generated by the parity check matrix generation unit 213 is H, the parity check matrix H includes H_(I) and H_(P), H_(I) is a matrix corresponding to an information word vector, and H_(P) is a matrix corresponding to a parity vector. H_(I) is a parent parity check matrix generated by the parent parity check matrix generation unit 211, and a quasi-cyclic matrix. H_(P) is an encoding matrix, and includes M′×L′ columns and M′×L′ rows. Here, H_(P) need not be a quasi-cyclic matrix, and may be one of a bit-wise dual diagonal (accumulator) matrix as shown in Equation (15), a block-wise dual diagonal matrix as shown in Equation (16), and a quasi-cyclic Block LDPC (BLDPC) used in an IEEE 802.16e communication system as shown in Equation (17).

If an information word vector includes k symbols and a parity vector includes m parity symbols, the parity check matrix generation unit 213 substitutes l×l (l=L/S1) permutation matrixes and l×l (l=L/S1) zero matrixes for permutation matrixes and zero matrixes included in a parent parity check matrix Q. The substituted permutation matrix is shown in Equation (18). p _(i,j) =f(P _(i,j) ,L,S1)  (18)

The parity check matrix generation unit 213 generates H_(I) including M block rows by separating each block row included in a conversion parent parity check matrix including the substituted permutation and zero matrixes, based on a row separation factor S2, or merging block rows included in the conversion parent parity check matrix matrixes, based on a row merge factor S3.

The parity check matrix generation unit 213 generates a parity check matrix as shown in Equation (19) by concatenating H_(I) and H_(P). H=[H _(I) |H _(p)]  (19)

In Equation (19), H_(P) includes M′×1 rows and M′×1 columns.

A permutation matrix is expressed in Equation (20). 1) f(P _(i,j) ,L,S1)=floor(P _(i,j) /S1) 2) f(P _(i,j) ,L,S1)=P _(i,j) mod(L/S1)  (20)

Although FIG. 2 illustrates the parent parity check matrix generation unit 211 generating the parent parity check matrix, the conversion information generation unit 215 generating the conversion information, and the parity check matrix generation unit 213 generating the parity check matrix using the parent parity check matrix and the conversion information, alternatively, the parity check matrix generation unit 213 may prestore the parent parity check matrix and the conversion information, and in this case, the parent parity check matrix generation unit 211 and the conversion information generation unit 215 are not utilized.

Additionally, Although FIG. 2 illustrates the parent parity check matrix generation unit 211, the parity check matrix generation unit 213, and the conversion information generation unit 215 as separate units, these components may be incorporated into a single unit.

TABLE 1 information word symbol 10, 20, 40, 80 number (k) code rate (k/n) 10/12, 10/14, 10/16, 10/18

In Table 1, which shows design requirement criterion for an MMT system, the information word symbol number denotes a number of information word symbols that the MMT system should support. That is, the MMT system should support four types of information word symbol number, i.e., 10, 20, 40, and 80.

In Table 1, the code rate denotes the code rate that the MMT system should support. That is, the MMT system should support four types of code rate, i.e., 10/12, 10/14, 10/16, and 10/18.

The four types of code rate for each of the four types of information word symbol number should be supported, so 16 parity check matrixes will be used if the MMT system intends to design all of the quasi-cyclic LDPC codes satisfying the design requirement criterion described in Table 1.

The information word symbol number (k) 10, 20, 40, and 80, as described in Table 1, are in multiples one another, so a required parity symbol number for satisfying the code rate (k/n) 10/12, 10/14, 10/16, 10/18, as descried in Table 1, are also in multiples of one another if the information word symbol number is determined.

In accordance with an embodiment of the present invention, the design requirement criterion in Table 1 is satisfied by performing a scaling operation and a row separation operation on a parent parity check matrix including 16(=2×8) rows and 80(=10×8) columns, which is generated by substituting an 8×8 permutation matrix for each element included in a base matrix including 2 rows and 10 columns.

For a base matrix expressed as in Equation (21), when the number of rows is 2 and the number of the columns is 10, a parent parity check matrix, which is generated by substituting an 8×8 permutation matrix for each element included in the base matrix in Equation (21), is expressed as shown in Equation (22). R ₀={0,1,2,3,4} R ₁={5,6,7,8,9}  (21) T ₀={(0,0),(1,7),(2,4),(3,1),(4,6)} T ₁={(5,3),(6,0),(7,1),(8,6),(9,7)}  (22)

A method for supporting various information word symbol numbers using a scaling scheme will be described with reference to a case in which a criterion 2) in Equation (20) is applied to the parent parity check matrix expressed in Equation (22).

information word symbol numbers 10, 20, and 40 may be supported by applying a permutation matrix substitution, in which a scaling factor S1=8, 4, and 2 is applied to the parent parity check matrix expressed in Equation (22), respectively.

Matrixes generated by applying a permutation matrix substitution, expressed as criterion 2) in Equation (20), in which a scaling factor S1=2 and 4 is applied to the parent parity check matrix expressed in Equation (22), respectively, are expressed as shown in Equations (23) to (24). T ₀={(0,0),(1,3),(2,0),(3,1),(4,2)} T ₁={(5,3),(6,0),(7,1),(8,2),(9,3)}  (23) T ₀={(0,0),(1,1),(2,0),(3,1),(4,0)} T ₁={(5,1),(6,0),(7,1),(8,0),(9,1)}  (24)

Parent parity check matrixes that support information word symbol numbers 40 and 20 are expressed in Equations (23) to (24), respectively. If the number of information word symbols is 10, L′=L/8=1. Therefore, a parent parity check matrix is equal to a base matrix as expressed in Equation (21).

If the number of information word symbols is 80, parity symbol numbers that satisfy the design requirement criterion in Table 1 are 16, 32, 48, and 64 for 10/12, 10/14, 10/16, and 10/18, respectively. In an LDPC code, the number of parity symbols is equal to the number of parity check equations. Therefore, a code rate is 80/(80+16)= 10/12, if the parity check matrix in Equation (22) is used as a parent parity check matrix, and the code rates described in Table 1 are satisfied if each row included in the parity check matrix is separated into 2, 3, and 4 rows, respectively.

A row separation patter may be designed in various forms. However, in accordance with an embodiment of the present invention, a rule provided below is applied in order to provide a uniform degree of distribution for the columns in a parity check matrix, which is generated by applying a row separation scheme.

<Row Separation Rule>

The jth row among rows that are generated by separating T_(i)={(t_(i,0),e_(i,0)), (t_(i,1),e_(i,1)), . . . , (

x

As described in Table 1, the MMT system may support the number of information word symbols 3200, 1600, 800, and 400 by performing a scaling factor S1=2, 4, 8, and 16 on the parent parity check matrix as shown in Equation (29).

If each row included in the parent parity check matrix as shown in Equation (29) is separated into 2, 3, and 4 rows, respectively, the design requirement criterion described in Table 2 may be satisfied.

Matrixes that are generated by applying the row separation rule (n=2, 3, and 4) described with reference to Table 1 to the parent parity check matrix as shown in Equation (29) are as shown in Equation (30) to Equation (32).

Therefore, code rates that the matrixes expressed as Equation (30) to Equation (32), i.e., the separated parent parity check matrixes, support are 20/22, 20/23, and 20/24, respectively.

FIG. 5 is a block diagram illustrating a quasi-cyclic LDPC encoder according to an embodiment of the present invention.

Referring to FIG. 5, a quasi-cyclic LDPC encoder 111 includes an information word vector convertor 511, a parity vector generator 513, and a quasi-cyclic LDPC codeword vector generator 515.

Upon inputting an information word vector, the information word vector convertor 511 generates a converted information word vector by performing a conversion operation on the information word vector, based on control information and a parity check matrix, and outputs the converted information word vector to the parity vector generator 513. For example, the conversion operation may be a padding operation in which zeros are inserted into the information word vector, based on the control information and the parity check matrix.

The parity vector generator 513 converts the information word vector output from the information word vector convertor 511 into a parity vector based on the control information and the parity check matrix, and outputs the parity vector to the quasi-cyclic LDPC codeword vector generator 515. The quasi-cyclic LDPC codeword vector generator 515 generates a quasi-cyclic LDPC codeword vector by concatenating the parity vector and the information word vector, based on the control information.

Alternatively, the quasi-cyclic LDPC codeword vector generator 515 may generate the quasi-cyclic LDPC codeword vector by concatenating a converted parity vector and the information word vector. The converted parity vector is generated by puncturing the parity vector.

FIG. 6 is a block diagram illustrating a quasi-cyclic LDPC code decoder included in a signal reception apparatus in an MMT system according to an embodiment of the present invention.

Referring to FIG. 6, a quasi-cyclic LDPC code decoder includes a quasi-cyclic LDPC decoder 611 and a parity check matrix generator 613.

A received vector is input to the quasi-cyclic LDPC decoder 611. For example, the received vector may be a quasi-cyclic LDPC vector output from a quasi-cyclic LDPC encoder. Control information including (k,n,m) information is input to the quasi-cyclic LDPC decoder 111. The control information is described before, so the detailed description will be omitted herein.

The parity check matrix generator 613 also inputs the control information, converts a prestored base matrix into a parity check matrix, based on the control information, and outputs the parity check matrix to the quasi-cyclic LDPC decoder 611.

The quasi-cyclic LDPC decoder 611 generates a recovered information vector by quasi-cyclic LDPC decoding the received vector, based on the control information.

Although FIG. 6 illustrates the parity check matrix generator 613 generating the parity check matrix and outputting the parity check matrix to the quasi-cyclic LDPC decoder 611, alternatively, the quasi-cyclic LDPC decoder 611 may prestore the parity check matrix, and in this case, the parity check matrix generator 613 is not utilized.

Although FIG. 6 illustrates the control information being input from the outside to the quasi-cyclic LDPC decoder 611 and the parity check matrix generator 613, alternatively, the quasi-cyclic LDPC decoder 611 and the parity check matrix generator 613 may prestore the control information.

While the quasi-cyclic LDPC decoder 611 and the parity check matrix generator 613 are illustrated in FIG. 6 as separate units, alternatively, these components may be incorporated into a single unit.

Although not illustrated, the signal reception apparatus includes the quasi-cyclic LDPC code decoder and a receiver, and the quasi-cyclic LDPC code decoder and the receiver may be incorporated into a single unit.

FIG. 7 is a flow chart illustrating an operation process of a quasi-cyclic LDPC code generator included in a signal transmission apparatus in an MMT system according to an embodiment of the present invention.

Referring to FIG. 7, in step 711, a quasi-cyclic LDPC code generator receives an information word vector and control information. In step 713, the quasi-cyclic LDPC code generator generates a quasi-cyclic LDPC codeword vector by performing a quasi-cyclic LDPC encoding operation on the information word vector, based on the control information. The quasi-cyclic LDPC codeword vector includes an information word vector including k information word symbols and a parity vector including m parity symbols.

FIG. 8 is a flow chart illustrating an operation process of a quasi-cyclic LDPC code decoder included in a signal reception apparatus in an MMT system according to an embodiment of the present invention.

Referring to FIG. 8, in step 811, a quasi-cyclic LDPC code decoder receives a received vector and control information. In step 813, the quasi-cyclic LDPC code decoder recovers an information word vector by quasi-cyclic LDPC decoding the received vector using the control information and a parity check matrix.

As is apparent from the foregoing description, various embodiments of the present invention provide quasi-cyclic LDPC code transmission and reception supporting various codeword lengths and code rates in a multimedia communication system.
